orthogonally mounted model 1010 accelerometers which feature

micromachined capacitive sense element, a custom integrated circuit sense

amplifier and sigma-delta A/D converter. It provides a TTL/CMOS compatible

output signal for measuring accelerations in commercial/industrial environments

and is tailored for zero to medium frequency instrumentation applications. The

anodized aluminum case is epoxy sealed and is easily mounted via two #8 (or

M4) screws. It is relatively insensitive to temperature changes and gradients. An

optional calibration sheet (2420-CAL) and periodic calibration checking are also

available.

OPERATION

The Model 2420 produces three digital pulse train outputs in which the density of pulses (number of pulses per

second) is proportional to applied acceleration. It operates from a single +5 volt power supplyand a100kHzto 1MHz,

TTL/CMOS compatible, clock. Each of the three outputs are ratiometric to the clock frequency and independent of

the power supply voltage. The "Z" axis is perpendicular to the bottom of the package, with positive acceleration

defined as a force pushing on the bottom of the package. The "X" and "Y" axis directions are marked on the cover

with positive acceleration defined as acceleration in the direction of the axis arrow. External digital line drivers can

be used to drive long cables or when used in an electrically noisy environment.
